ARG0003gy1, doublelobe, nat

  • ChrisMolloy by ChrisMolloy

    Here's ARG0003gy1, which appears in First to be a #bent, #looping, #doublelobe and possibly a #nat. This ARG field has previously been cited in the post, An interesting find.

    The contour overlay image in this post was created from sources, and using methods, described in this RGZ Talk
    thread.     First in red.

    The host for the emission appears to be SDSS J103938.71+051032.5. NED cites this galaxy as having a z_sp=0.067900, radio references in NED and SIMBAD, and an ALLWISE reference, ALLWISE J103938.79+051032.1.

    There is also a radio reference in NED for SDSS J103938.96+051031.3, which has a z_sp=0.068 +/-0.00002. This object is slightly ESE of SDSS J103938.71+051032.5.

    This ARG field has also been imaged in VLASS, below. It appears to have a slightly different morphology from the First contour above. The faint looping lobes to the NW, and trailing off SW, do not appear apparent.

    thread.     VLASS contours in yellow.

    Finally, it should be noted that this ARG field is in a #cluster environment.

    As always, comments, suggestions, welcome.

    Indeed an interesting field! 😃

    I think the VLASS overlay points more strongly to SDSS J103938.71+051032.5 being the host (it may be the BCG, the brightest cluster galaxy), and I think that "cluster environment" has a lot to do with creating the weirdness of the radio morphology.
